but you splitting your developer base. * There will be people better at kotlin * There will be people better at java.

This is a problem when you are looking at hiring new people etc . This fragmentation is going cause issues just because people are hedging against Oracle future decisions.

In a perfect world Google should have bought Sun and the current version of Java would look at lot like Kotlin.

Kotlin is a light syntax for a coding style. It's as easy for a Java dev to learn Kotlin as it is to learn Spring or Hibernate or whatever library or framework the team at your new job uses

It's a whole other domain of things to learn, and now we're stuck with context switching all of the time.

Even if Kotline were 'better' (And I don't think it is), it'd have to be quite a jump better.

It's a little nicer for getting ideas down quickly, but beyond that to me it's just 'different' and now a whole other bag of things to support.

If I have to chose between Kotlin+Java or just Java I'll take just Java.

Going back to Java from Kotlin there's really nothing I miss.
